First Appearance:


Speedline is the Antitrix's DNA sample of a Citrakayah/Appoplexian hybrid, and is Kevin's equivalent to Fasttrack. He is a free use alien made by Alan.




  • Like Fasttrack, Speedline has enhanced speed. With his Appoplexian strength, he can concentrate his speed in a singular direction to go faster than normal.
  • Speedline can combine his strength and speed for kinetic-based combat.
  • Speedline has fur blades and sharp claws.
  • Speedline has enhanced durability and agility.


  • Due to his Appoplexian DNA, Speedline has fits of anger at times.
  • When using his uni-directional speed, Speedline has a difficult time changing direction.
  • Due to his increased muscle mass, Speedline is somewhat slower than Fasttrack.


If Bangolin appears in your series, add it here!



  • A speedline is an artistic term for a visual expression of speed, such as the blue and black blurs that XLR8 and Fasttrack leave when utilizing their powers. It is also a pun on Speedline's uni-directional speedpower, as he goes in a line.


  • Speedline's uni-directional speed was somewhat inspired by Aaron's alien, Speedbump.
