Aurora

So generally anyone who has good CC and can lock enemies down is amazing for Aurora. Peely frontlines are nice too, especially since if you're going attack speed you won't get as much health as you would if you had items like Riftmaker or Cosmic Drive

Leona

Leona can roam very well during laning phase, and you can secure kills together extremely easily once you both have level 6. She compensates for your squishiness and offers excellent lock-down potential on enemy champs. If you're playing Aurora as a botlane carry she's a great support for the same reasons.

Skarner

Skarner also has great lockdown and tankiness that make his ganks super good for Aurora. Just let him take the aggro and tank/cc while you pelt them with autos and your QE combo.

Galio

Galio's tankiness and ability to frontline along with his amazing ganks and teamfight potential work really nicely with your squishy but mobile and damaging champ.

Poppy

Wukong

If you can poke your enemy down a bit and then bait them into pushing up lane Wukong's ganking potential with your kit is very nice. His ultimate synergises well with yours in teamfights too.

Naafiri

Your engage and chase potential together is absolutely disgusting.

Alistar

Alistar's mixture of CC and ability to frontline for you is very nice - another strong contender for support if you're playing in botlane, and very useful in teamfights regardless of what lane you pick.

Rammus

Rammus has basically everything you could want from a jungler as Aurora - great speedy engage and chase, tankiness, and reliable CC in the form of his taunt.
