The Guyvers abilities are judged out
of ten by how well they fought against Zoanoids and Hyper Zoanoids in my opinion:
Combat abilities in general:
guyver
Speed. 7.5
Strength. 8.9
Defence. 6.4
Offence. 9.2
The Bio-Booster Armour is activated when the person
who has merged with the G-unit calls on it. They usually shout "Guyver!" or "Bio-Boost" when calling on the Guyver.
These battle ratings shown in the previous paragraphs/pages
are my opinion of how effective the Guyver's weaponry is, this is not official.
