BOSS
THE PERFECT CYCLONE
Revenge of Red Sky is the 3rd stage of Red Sky at Morning. Previous stage: Wrath of Red Sky.
STRATEGY
A limited set of buffed Angels covers The Perfect Cyclone's small blindspot, and Sleipnir shoves anything that gets inside back into the Cyclone's effective range.
- Outrange the Cyclone instead: wait until Sleipnir walks ahead of it, chip Sleipnir with backliners, then finish the Cyclone. Leave the base alone until the Hippoes and Gory are dead.
- Cyberpunk Cat with a full Slow Talent (1,200 standing range, 800 blindspot) delays both main threats; add Sniper the Deadeye and the slow uptime is nearly 100% — but Deadeye knocks Sleipnir back, which ruins luring plans.
- Ramen Cat stalls the Angels and out-tanks Dual Erasers against the Cyclone and Sleipnir, though its slow speed makes it a poor Cyclone fighter.
- Dragon Cat variants (King Dragon, Manic, Li'l, Brainwashed) are the Uberless answer: lure Sleipnir into their range while something else pins the Cyclone — expensive, so mind your wallet.
- Maglev's burst is best spent finishing Gabriel after other attackers have whittled him down.

The Perfect Cyclone BOSS
The Perfect Cyclone has an enormous standing range of 650 but a blind spot of 250 range. However, despite the very obvious weakness, it is almost impossible to get close enough because of its insanely fast attack rate compared to other Long Distance Enemies, greatly increasing its DPS even with low attack power for a Cyclone.

CATS TO BRING 
CYBERPUNK CAT A Cyberpunk Cat - Fully upgrading Cyberpunk Cat's Slow Talent makes it exceptionally useful, as its 1200 standing range keeps itself safe while delaying the already slow main threats from advancing, although its massive 800 range blindspot must be accounted for. Stacking a few more Cyberpunks could potentially eliminate 
SNIPER THE DEADEYE A Sniper the Deadeye - Stacking this with Cyberpunk can create the ultimate wall against this stage, as this combined with a max slow talent Cyberpunk gives it almost 100% uptime. Combine it with another Cyberpunk and the stage is basically over, though this may not be optimal for strategies that involve luring the Sleip 
RAMEN CAT A Ramen Cat - Ramen is useful for stalling the Angels in any situation, although its slow speed makes it less than desirable when fighting The Perfect Cyclone as the Cyclone can cut down a lot of its HP quickly and destroy it, though thanks to his naturally high bulk he can sustain more hits than Dual Erasers against Per 
KING DRAGON CAT B King Dragon Cat/Manic King Dragon/Li'l King Dragon Cat/Brainwashed Dragon Cat - Used in many Uberless strategies, Dragon stacks rely on luring Sleipnir within their range and using something else to pin The Perfect Cyclone (standing range is identical to maximum effective range), slowly damaging Sleipnir and replacing 
MANIC KING DRAGON A King Dragon Cat/Manic King Dragon/Li'l King Dragon Cat/Brainwashed Dragon Cat - Used in many Uberless strategies, Dragon stacks rely on luring Sleipnir within their range and using something else to pin The Perfect Cyclone (standing range is identical to maximum effective range), slowly damaging Sleipnir and replacing 
LI'L KING DRAGON CAT B King Dragon Cat/Manic King Dragon/Li'l King Dragon Cat/Brainwashed Dragon Cat - Used in many Uberless strategies, Dragon stacks rely on luring Sleipnir within their range and using something else to pin The Perfect Cyclone (standing range is identical to maximum effective range), slowly damaging Sleipnir and replacing 
BRAINWASHED DRAGON CAT A King Dragon Cat/Manic King Dragon/Li'l King Dragon Cat/Brainwashed Dragon Cat - Used in many Uberless strategies, Dragon stacks rely on luring Sleipnir within their range and using something else to pin The Perfect Cyclone (standing range is identical to maximum effective range), slowly damaging Sleipnir and replacing 
MAGLEV CAT A Maglev Cat - An excellent complement to any strategy, Maglev's damage burst is best used with other attackers by letting them whittle Gabriel before sending it for the kill. Maglev's high speed ensures they can easily make it inside the blindspot, and if Sleipnir does not kill it quickly, it may get at least one extra 
CLEANERBOT CAT A Cleanerbot Cat - This defensive unit's main highlight is its very high health, singular knockback and its knockback immunity which prevents Sleipnir from pushing it. Its long cooldown means it should never be your only option, but when aided by others can create a thick line of defense. 
OCTOPUS CAT A Octopus Cat - Octopus' lower cooldown, singular knockback and resistance to Floating enemies makes it a great option for covering your other units against The Perfect Cyclone and helps to finish the stage with its ability to weaken Floating enemies. 
HEADMASTER CAT JOBS A Headmaster Cat Jobs - Allows you to almost infinitely stall a Heavenly Hippoe with the help of weaken combos. Perfect for stacking Long Distance units like Cyberpunk. 
LUFALAN PASALAN S Lufalan Pasalan - Lufalan Pasalan has very long range (720), enough to reach The Perfect Cyclone safely. It also makes Sleipnir easier to deal with. And since you are fighting an endurance battle here, the Gabriels that come once in a while won't be that big of a problem despite its single target. Make sure it's spawne 
SABER THE CAT C Saber Alter Cat: Strong against Floating enemies (Deals 1.5x damage, only takes 1/2 damage) 
ARCHER CAT A Deals Massive Damage to Floating enemies. 
BODHISATTVA CAT A Slows and (True) Weakens Floating enemies. 
CATMAN S Massive Damage vs Floating (Normal). 
HIGH LORD BABEL S Equally tough against Floating enemies, with Colossus Slayer. 
BAHAMUT CAT S Huge multi-hit burst — a story-unlock powerhouse that deletes tanky enemies. TECOLUGA S A 7,300-AP long-range hit obliterates tanky targets when the Critical connects. Also fits “Out-range The Perfect Cyclone.” 
GAIA THE CREATOR S Long-Distance multi-hit with Insane Damage — a generalist wall-cracker. 
CRAZED MONEKO A Big crit burst against tanky/Metal targets. 
CHILD OF DESTINY PHONO S Big Multi-Hit Massive-Damage bursts from safety.
