"I remember it... this is... death. An enemy indefinitely stronger than me... and the terror I feel facing it"
Frog wore a simple dark-colored robe and small red rectangular glasses.
Frog was confident and had an air of authority, as well as that of being an elderly individual given his choice of personal pronoun "washi" (わし, 儂) being that often stereotypically used to represent old characters in fiction.
Little is known about Frog's former life prior to being a Chimera Ant, not even he himself knew much if anything about it. However, he recalled having felt an extreme sense of overwhelming dread as he died, presumably at the hands of Chimera Ant Queen or her underlings.
Chimera Ant arc
While the Squadron Leaders are summoned by the Chimera Ant Queen in the Chimera Ants' nest, Frog is seen reading a newspaper. At a later time, Frog, Baro, Rhino, and some other Chimera Ants confront Gon, Killua, and Kite in the NGL forest, where he gives the group three choices:
- Decide an order in which they can fight them.
- Try and escape.
- Give up and surrender to them.
Presumably, if they chose option 1, they would choose a representative from their side to fight them individually with a small chance of survival. If they chose option 2, that would be annoying to them and they would soon catch them and torture them. Finally, if they chose option 3, which he doesn't recommend, would make the previous choice be far less annoying. So Kite and group choose option 1. Gon and Killua both kill their respective opponents Baro and Rhino, agitating Frog and so he volunteers to fight against Kite. However before he could make a move, Kite uses his Crazy Slots ability summoning a giant scythe that in an instant, slices off Frog's head causing him to remember the feeling of death.
