Katarina Alves (カタリーナ・アウヴェス Katarīna Auvesu?) is a character in the Tekken series introduced in Tekken 7 as one of the five initial newcomers to the series. Katarina is an aggressive and sassy-mouthed talker with a cocky and slightly flirtatious personality. She did however greatly respect her adoptive father, who recently disappeared and was transformed into G Corporation's brainwashed, mutated human, Gigas.

Katarina seems to be very confident in her abilities as a fighter; alongside her cocky attitude, her fighting pose has her guard totally lowered (contrary to a traditional savate stance), and her posture is completely relaxed. Katarina Alves lost both her parents at a young age, and spent several years at an orphanage before being adopted by a man she'd never met. Initially, Katarina rebelled against him, using a whole manner of profane language, but the man's kindness and patience eventually wore her hard exterior down.

In time, they grew close, though her penchant for profane language remained. One day, Katarina's adoptive father vanished. As much as she wanted to find him, she lacked the money to do so. But then, she learned of the King of Iron Fist Tournament. The savate techniques the man had taught her gave Katarina hope that she could win and take the cash prize. The day of the first match arrived, and the arena was none other than the roof of G Corporation's Millennium Tower.

When Katarina first laid eyes on her opponent, all she saw was an enormous hulk of muscle. There was no way he could be human... Ending Description: Having finally defeated Gigas in battle, Katarina removes her sunglasses and approaches her fallen opponent. Gigas recognizes who she is as Katarina readies herself to attack. As she does so, a G Corporation soldier appears from behind and opens fire. A bullet grazes her shoulder. but Gigas defends her by blocking further bullets. He charges towards the soldier and both are knocked off the tower as Katarina looks on.
