As he's written I'd say he's probably somewhat high-level but still not that much more powerful then other high-level characters in the RP.

Again, I just want to confirm that the "power up from near death" thing won't drive him to casual planet destruction levels, as with his personality you can't really excuse him not using it.

Frieza is the first character seen that is capable of blowing up entire planets. His power level is 530,000. Let's use 500,000 as a reasonable marker for planet-destroying power.

Assuming a zenkai doubles the Saiyan's power (it doesn't, not even close, but it's an acceptable unit of measurement for this example), Raditz at 1,200 would need to have at least nine near-death experiences to be able to blow up a planet. It's not feasible simply because of the ridiculous inefficiency. In addition, a near-death experience is exactly what it says on the tin. Any competent fighter will remove the 'near' from the equation.

Your scenario, while theoretically not impossible, is astronomically unlikely.
