Two Esbarels in Stage 1
The Esbarel (エスバレル Esubareru) is what you can call the "Basic Fighter" of the Ver'mith Fleet. This Airborne unit is an easy-to-defeat target, but it can be captured too. Teamwork seems to be a programmed behavior on the Esbarels because this enemy always appear flying in pairs or large formations, but never seen flying alone.
A single Esbarel gives you 69t to the Weight Point bonus, and it takes 50% per frame of a second to be captured by the Anchor Unit.
This enemy appears in the stages 1, 2, 3 and 5 (and Stage 0 in Triggerheart Exelica Enhanced). They also appear in the imode mini-game Kumash!
