Recommended Typhlosion moveset

I'd say:

Typhlosion+Leftovers

Flamethrower
Focus Blast
Thunderpunch
Earthquake

A good, powerful moveset for you there! Sorry no nature but I don't think it's gonna matter too much unless you are gonna EV train it.

That's kinda like what Saints Fan said.
If it's ingame, I probably wouldn't worry about a nature.

my quilavia has no weakness because ive got thunder punch to take care of water,flying pokemon and ground,rock types, and a good fighting type move i cant remember thogh it myt be focus blast orfocus punch or u can just get the element punches or element blast

the best moves for typhlosion are Shadow claw,Eruption,Earthquake,Blastburn and probly one super awesome move of your choice

The best thing for any Typhlosion is to do some extreme Attack and speed training with power bracer and power anklet. And it's move set should Flamethrower,Thunderpunch,Quickattack, and Flareblitz or Eruption ur choice.(I chose flareblitz) See, Thunderpunch will be your ace in the hole for water types, so its good to have awesome attack power. And if You choose eruption u may need great speed as well so u can use the move before typhlosion takes any hard damage. As for items, Give it a Muscle band, or expert belt. Trust me I know Typhlosion;)

For nature i don't know what to tell but mine is Bold

Mine is

Flamethrower
Rock Slide
Sunny Day (Heat Rock)
Solar Beam

Just playing to it's strengths really and Solarbeam eliminates it's 3 weaknesses too and Rock Slide...that was just to make sure he wasn't useless against lance but like i say it's your call boss.

you made Typhlosion an HM slave?!? SHAME

Mine has Lava Plume, Swift, Flamethrower, and ThunderPunch right now though it isn't at level 50 yet.
