Strength based Dommage and Alternate power.

[Spike31]

Hello.
I have some doubts about creating a power. I would like to know if it is possible (on the basis of a human and therefore with normal abilities).

Abilities (7 being the max for a human):
Strength: 3.
Fighting: 2.

Power:

The Tiger's Strength [17PP]:
Alternate effect.

- The tiger claws 1 PP [14PP], Strength based Damage (1/R), Enhanced Strength 1, Enhanced Advantage Improved Critical (Unarmed Attack) 4, MultiAttack (+1/R). Accurate 4 (4). Reach 2 (2).

- The tiger bite 1 PP [15PP], Strength based Damage (1/R), Enhanced Strength 7, Enhanced Advantage Accurate 1 (1).

-The tiger leap 1 PP [15PP], Strength Damage (1/R), Resisted by Dodge. Enhanced Strength 5, Teleport 3 limited to reach the target attacked from above (3). Enhanced Advantage . Accurate 2 (2)


For offensive play:
- The tiger claws Close Ranged Damage 4, +10, Crit: 16-20. Reach: 10 feet.
- The tiger bite Close Ranged Damage 10, +4.
- The tiger leap Close Ranged Damage 8, +6, Teleport Range: 250 feet.



I'd like to know if:
1): It's possible to create a series of alternates to have force-based attacks that can hit different targets (targets that are maxed out in parry or Toughness easily).
2): If I'm not mistaken in the costs.


Thank you in advance!


Ps:
if I want to add that power for a PL7 character, did I make a mistake (I have the advantage Improved Hold) ?
