Befitting Him being a fusion of Mizuki and Caerula Arbor (no pun intended), Izumik the Source of Ecology boasts humongous HP and DEF along with significant ATK and RES, allowing Him to shrug off all but the strongest of Physical and Arts attacks while causing destructive ranged damage in return. However, Izumik spends most of His time in a relatively passive state summoning minions, only retaliating or taking direct action once certain conditions have been fulfilled.

Unleashes a shockwave that Stuns all friendly units on the map for 8 seconds and inflicts them with a debuff that deals Arts damage equal to 12% of Izumik's ATK every second for the duration, which does not stack but will be refreshed if the affected unit is hit by the shockwave again.
Izumik will unleash the shockwave immediately after losing 25% of His maximum HP, even if it is on cooldown.
Unusually, camouflaged units are unaffected by the shockwave.
"Izumik" is an anagram of "Mizuki" and are likely derived from izumi (泉), "fountain" in Japanese, which is possibly a nod to His epithet as the "Source (i.e. "fountainhead" or "fount") of Ecology".
Mizuki's gamertag on Barrage Fortress, "IZUMIKun~~", is suspiciously similar with His name. The Childhood's End Memory Selection implies that Mizuki arbitrarily named his alternate timeline Firstborn self after his gamertag, after communicating with Him through non-linear time.
Even though Mizuki had assimilated with Caerula Arbor to resurrect the latter as Izumik, the former can actually be used on Glory of Humanity where Izumik is fought.
