To the anon, in the Tiga movie Revival of the Ancient Giant, Amui \was a child. But he was able to fully transform into Tiga. In comparison, Tsubasa Madoka, in spite of being Daigo's son and an adult, could only transform into a Tiga who was half his normal size and much weaker.

I'd say the host's age has nothing to do with the Ultra's power.
