Health: 41-44 (Level 98-99)
Ki: 50-75 (Level 89-98)
Stamina: 52-75 (Level 82-90)
Basic Attack: 100
Strike Supers: 0
Blast Supers: 0

Core: Hyper Drain, Phantom Fist/Afterimage Strike
Others: Instant Transmission, Maximum Charge, Super Drain, Arm Crash, Gravity Impact

First: Super Saiyan/2
Second: any (Blue Hurricane seems to be capable of one- or twoshotting Giant Apes regardless of your Strike Supers stat)

The idea is simple enough: Male Saiyans have the highest basic attack stat in the game, and Super Saiyan simply acts to boost that even more. The execution is a little harder because you won't get any op damage out of abilities, but you can easily pull off an infinite loop combo in midair by using a few light attacks followed by two heavy attacks (should stand still when initiating the combo).

(- Master-related Z-Soul depending on your Ultimate of choice)

Health: 20
Ki: 75-100 (Level 91-99)
Stamina: 50-75 (Level 83-91)
Basic Attack: 0
Strike Supers: 0
Blast Supers: 100

Core: Maximum Charge (or Hyper Drain), Phantom Fist/Afterimage Strike
Decent: X10 Kamehameha, DIE DIE Missile Barrage, Crusher Ball, Perfect Shot
Optional: Counter-Burst, Gravity Impact, Spirit Bomb, Kamehameha

First: Super Vegeta/2 (or Super Saiyan if you don't have Super Vegeta)
Second: Crusher Volcano, Teleporting Vanishing Ball, Sphere of Destruction, Final Flash, Final Shine, Super Spirit Bomb, Perfect Kamehameha, Warp Kamehameha... you get the point.

Probably the easiest playstyle for PvE - just go Super Saiyan and spam your other Ultimate (and maybe some Supers for a change of pace). Afterimage Strike is fun because you can cancel out of it into your Ultimate of choice, and you can probably keep up SSJ indefinitely by comboing into a Hyper Drain. One of the best Supers you can use is DIE DIE Missile Barrage (insane tracking and decent damage at medium range), and the best Ultimates (in my opinion) are Crusher Volcano and Teleporting Vanishing Ball, or any one you have a Z-Soul for.

Health: 29
Ki: 0
Stamina: 75
Basic Attack: 36-90 (Level 81-99)
Strike Supers: 100
Blast Supers: 0

Core: X3/X20 Kaioken, Super/Hyper Drain
Decent: Rebellion Spear, God of Destruction's Rampage, Super Dragon Fist
Usable: Super Dragon Flight, Meteor Crash, Arm Crash, Phantom Fist/Afterimage Strike, Rise to Action

Best: Blue Hurricane, Victory Rush
Options: Unrelenting Barrage, Death Meteor

You don't have to use Kaioken, and if you do I strongly recommend X3 as X20 has the same damage boost with the only advantage being free Evasive Skills. If you don't like Kaioken or can't manage to combo into Super/Hyper-Drain, it's okay to use something like Phantom Fist or Afterimage Strike instead. Male Earthlings have the best Strike supers in the entire game, autocharging Ki and deal more damage when Ki is full, which means basic attack is a decent secondary offensive stat for them - and with Kaioken draining Stamina instead of Ki, that's a pretty strong combo. Considering how many amazing Strike supers you can choose from, I prefer to get 100 in that first and foremost.
Also, this is by far the best build to farm Giant Apes with Blue Hurricane, although you don't really need to max out Strike supers to do that.
