You need to grind for it again according to ku devs, its becuase of how much more power shes getting, shes going from an early game kaiju to a late game or endgame kaiju.
I think the requirements should be level 89 hesei since it appeared in 1989 and rose bio to 50 kills and also to have the same amount of g-cells that minus one had
Nah dude Biollante looks like it’s going to be endgame so I would assume the requirements would be level 100 Rose Bio, 600k g cells, 100 Heisei and possibly other requirements like finding roses across the map but this is only a mere speculation.
Yeah I saw not that hard I casually got destoroyah which was harder to get plus people the secret ability at level 25 for rose bio is op to get level 75
i get that it is a endgame kaiju but ku reqs are getting too annoying. i would make it: rose bio lvl 50, lvl 50 or 30 heisei godzilla and some kind of king of the hill to get erika dna
