- Street Fighter III: 2nd Impact: Vs. Rival (Character-Specific)
If you manage to get 5 Super Art Finishes without using any continues, then you’ll face your rival after defeating your current opponent. In Ibuki’s case, it’s Elena, but every character has their own specific rival (Sean’s rival, for example, is Yang). This is also the only possible way to face that character, as they’ll never appear in your character’s Arcade Mode otherwise. The fight itself isn’t special in any way though, except for the fact that the fight takes place on the same stage as the previous match instead of your rival’s home stage. Once you’ve defeated your rival, the game will progress normally again.

- Street Fighter III: 2nd Impact: Vs. Akuma
If you manage to get at least 2 Perfects without losing a single round, then you’ll be able to face Akuma. Once you reach your character’s final opponent, Akuma will suddenly appear and use the Raging Demon on them, taking their place as your final opponent. In 2nd Impact, Akuma is very powerful. He’s one of the best characters in the game and his AI can be very difficult to deal with. That said, he has two major weaknesses: low health and a small stun bar. In Ibuki’s case, her F + HK Command Normal (Bonshou Geri) and her Cr. HP both deal good damage and a lot of stun, with the former being great for Whiff Punishing and the latter being a great Anti-Air. Aside from these two, use Cr. MK to slide under Akuma’s Gohadoukens to get in more easily. Akuma also tends to use his Tatsu a lot on block, so you can punish him for that if you’re quick enough. Finally, Akuma’s AI tends to use Goshoryuken a lot as an Anti-Air, so if you jump in and parry it, you get a free punish. Once you defeat Akuma, one of two things will happen: either the match ends and a special ending plays, or you’ll be able to face Shin Akuma if you met the necessary requirements.

- Street Fighter III: 2nd Impact: Vs. Shin Akuma
If you manage to get at least 3 Perfects, get no more than 3 Cheap Wins and not lose a single round, Akuma will transform into Shin Akuma after defeating him with at least one Super Art Finish. Shin Akuma is basically a more powerful and faster Akuma with an even cheaper AI. Despite that, he still has low health and a small stun bar, so his weaknesses are the same. Just play it a little safer and you should be able to beat him the same way you beat regular Akuma. After you defeat Shin Akuma, you’ll get a different special ending that reveals Gill survived Akuma’s Raging Demon via Resurrection.

- Street Fighter III: 3rd Strike:
If order to face Q, you’ll need to meet quite a few requirements. You have to get at least 5 Super Art Finishes and 2 Special Points, you can’t lose a single round and you can never get a lower rank than a D. After meeting these requirements, you’ll be able to face Q after you beat your 7th opponent, signified by him briefly appearing on-screen. This is the only possible way to fight him as an AI opponent, as Q never appears during Arcade Mode otherwise. The fight will take place on the same stage as the previous match, but this time with Q’s theme playing. As for the fight itself, the AI-controlled Q is no different from a player-controlled Q in terms of strength. So if you know the matchup, then he shouldn’t be a problem. Once you’ve defeated Q, the game will progress normally again.

- [BONUS] Street Fighter III: 3rd Strike: Vs. Shin Akuma (Unused)
Even though Shin Akuma never actually appears in 3rd Strike normally, he is still present in the game’s coding and almost fully functional. If you’re using MAME, then you can use the MAME cheat folder to fight against him or use him yourself if you want to (you can also select his unused stage this way). Since he doesn’t have his own character art, he uses Chun-Li’s instead. He’s exactly the same as 2nd Impact Shin Akuma moveset-wise, so he doesn’t have any of 3rd Strike Akuma’s moveset changes and additions. A couple of his moves are somewhat glitched however, mainly his Tatsu (both versions), his SAII and his SAIII. His Tatsu has some glitched animation frames and the aerial version seems to lack a hurtbox (it does have a hitbox though, which makes his air Tatsu impossible to counter). His SAII will occasionally cause him to freeze in place, though he returns to normal after a while. Finally, his SAIII sometimes fails to gain any height, keeping him relatively close to the ground. The fight itself is really hard (even harder than Gill from my experience) because of his high damage output and speed. Your best bet is to simply play it safe and try to find an opening when possible.

Hope you enjoy!
