Defense should be successful (The troll should have 2 extra dice for reach, I think, but even with those Rafa's defense scores at least an equal amount of hits). Agility 7 + Blade 4 + charging 2 + martial arts knockdown 1 + reach 2 + Extra speed on the charge bonus 1(optional - reserved for player characters)
Throw is an opposed test, Troll rolls Str + Unarmed vs Rafa's 7 hits. He's thrown a number of meters equal to net hits and takes stun damage accordingly.
Since I don't know the result, I'll let you fluff.
Was late and i really did not want to onshot Rafa, took off too much dice from the roll, wont hold back anymore though.

So You Want to throw Akuma(troll) that is charging at you with 53m/s and is like 250kg?
You bet this is gona be difficult.
This time around i will not hold off and will use the full dicepool,
also i thing that the situation calls for small modifiers - 3 on your test but +2 for damage because of his reach, size and speed.
your 7 hits stay anyway

and you succed
please feel free to post that way you see this happening. if i would do a direction dice would decide the place where The troll would land and i would be very disappointed if he lands on the Rover with Caretaker and Panther inside.
Str 13 + unarmed 4 (17d6.hits(5)=3)
