Update 54 adds Heisei Mothra Larva and Heisei Mothra. The developer clarifies that the previously removed Mothra was Showa. Godzilla in Hell receives several reductions and a stronger Devil Bat Power attack.

Both Heisei Mothra Larva and Heisei Mothra are listed in the current Roblox description. The naming distinction matters: an old Showa Mothra entry is not a current unlock guide for the new Heisei form.

Godzilla in Hell: before and after
The description does not give a unit or a longer explanation for Immortal Apocalypse. We preserve its numeric change without interpreting it as lives, duration or a cooldown.
| Move or property | Before | After |
|---|---|---|
| A1 (1, 2), maximum damage | 690 | 640 |
| A2, maximum damage | 980 | 900 |
| A5, maximum damage | 400 | 385 |
| A3 Special, maximum damage | 300 | 200 |
| A5 Special — Devil Bat Power | 350 | 450 |
| Immortal Apocalypse | 2 | 1 |
What to reconsider after this patch
A Godzilla in Hell recommendation based only on the earlier damage values needs another look. Most listed attacks were reduced, while Devil Bat Power moved in the other direction; “everything was nerfed” would miss that exception.
For new Mothra unlocks, use the current in-game names. This patch note confirms the additions but does not publish their purchase costs. A price copied from an older Showa card would answer a different question.
