INFERNAL TYRANT CLIMAX
Infernal Tyrant Climax is the 4th stage of Reign of the Tyrant. Previous stage: Infernal Tyrant 3.
Almost every enemy that does not spawn infinitely is a serious threat in its own right.
- M. Ost pushes with terrifying ease, the Sir Rels tear through your line, and Two Can's Waves are a handful.
- Even Ragin' Gory, normally easy to answer, is dangerous in the opening moments.
- Bring answers for those specifically, remove them fast, and only then work on Nyandam.
- The start is tight on cash, so a Rich Cat and Sniper the Cat both earn their slots.
Behemoth 
4.67M HP Aku boss and the hardest hitter in the Advent set. Its first Multi-Hit lands 666,666 damage at -400~400 Omni Strike; the 2nd and 3rd hits reach 500~800 and 1,000~1,250 and are Toxic, stripping 30% of a Cat Unit's maximum health each. Immune to Knockback, Weaken and Surge.
Infernal Tyrant Nyandam is Aku. Anti-Aku units take less damage and deal more.
BOWLER CAT A Also slows Aku enemies, a handy specialist pick for early Aku Realms stages. 
BRAINWASHED COW CAT A Curses Aku enemies, shutting off their abilities. 
HEAVENLY GOD SUPER ZEUS S Slows and resists Aku enemies. Also fits “Out-range Infernal Tyrant Nyandam.” 
MAIZE CAT A Resistant to Aku — durable against Aku attackers. 
NYMPH CAT A True Form knocks back Aku enemies. Infernal Tyrant Nyandam reaches 400 range. Units that out-range it can chip safely without taking hits.
RED RIDING MINA A Range 435 — fires from beyond its 400. 
NERD CAT A Range 1200 — fires from beyond its 400. Also fits “Clear the crowd.” 
MIGHTY REKON KORPS S Range 470 — fires from beyond its 400. Also fits “Burst the boss down.” 
MEDITATION CAT C Range 600 — fires from beyond its 400. 
CRAZED LIZARD CAT A Range 415 — fires from beyond its 400. Infernal Tyrant Nyandam has a deep HP pool (4,666,666+ even before stage magnification). Heavy single-target burst shortens the fight.
BAHAMUT CAT S Huge multi-hit burst — a story-unlock powerhouse that deletes tanky enemies. MIGHTY REKON KORPS S Among the highest single-hit Area damage available. Also fits “Out-range Infernal Tyrant Nyandam.” 
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. Also fits “Out-range Infernal Tyrant Nyandam.” 8 enemy types stack up here. Area attackers hit the whole push at once instead of one unit at a time.
VALKYRIE CAT A Hits the whole group while it freezes them. 
SALON CAT S Hits whole crowds, and is Weaken-immune so it keeps firing through Weaken stages. NERD CAT A Evolved/True hit groups over a Long Distance band. Also fits “Out-range Infernal Tyrant Nyandam.” MIGHTY REKON KORPS S Long-range (Omni Strike in True) Area clears groups front and back. Also fits “Out-range Infernal Tyrant Nyandam.” 
ACTRESS CAT B Hits multiple enemies at once for budget crowd damage. The castle you destroy to clear the stage.
