In the interest of fairness, I'll use official multipliers. Oh, and Mystic > One Piece Bus Ride now by a few dozen posts. Time to reconsider that fight?
Base: 37 (Well, I'd stomp the Emperor Pilaf arc, I guess?)
Kaio-Ken x20: 740 (I'd sweep all of Dragon Ball before getting one-shot by Raditz.)
SSJ: 1,850 (I'm comparable to a human in the Vegeta fight.)
SSJ2: 3,700 (I'd be respected on Planet Vegeta and completely stomped after the Raditz Fight. I'm finally approaching the bases of the top tier.)
SSJ3: 14,800 (I'd do fairly well against Vegeta in the Saiyan Saga, but I'd lose eventually. I'd stomp anyone here in their base except Zoro, who might last a little while.)
SSJ4: 148,000 (I'd beat anyone up to Captain Ginyu and get killed by Frieza. I can beat anyone's Kaio-Ken x20 form except 2kewl4u and Zoro.)
Wow, this is a little depressing.
