T.B Rika is a new villain introduced in Otomedius Excellent. She pilots the Tri-Pod Core which is themed from the Parodius and Contra series.
- Probably, or not, she's Chichibinta Rika, or a descendant, since her last name is Rika and her theme song is a remix of "The Final Enemy".
- T.B. Rika is a scientist and a teacher of the St. Gradius High School (Anoa, Tron and Fuuma) but she has secretly joined the Bacterian Army as Spy Warrior and settled things up to destroy anything, even the Angel Squadrons.
