These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
The AI in the game thus far is severely limited in quality; while strategy is encouraged, the AI only ever seems to pick Lonestar, Clunk, Froggy G, and Leon and employ basic rush tactics and flee once their health gets low. This can make winning a practice match as characters like Voltar or Coco difficult.
Averted after the 2.6 patch. The AI can now use all the characters including the Starstorm Nauts. They are also a bit smarter, with support characters staying by teammates and backing them up.
"Down from the seas into space! Stretching his tentacles out, squirting them in your face!"
"Who's going to wreck this party? Who's gonna start a ruckus? Aylalalalalalala..."
"Ted McPaaiiiiin, True heroes never fade away..."
"She's an adorable scout, she is a true Awesomenaut. She is both clever and charmin', she is the darling of darlings. She is so foxy."
Game Breaker: Yuri can be this in the console versions with the right upgrades, with a time warp that can render droids and allies nearly invincible through healing, a laser long enough to hit a turret from a safe distance, and mines that do the most damage out of any attacks in the whole game. While he was nerfed in the PC version, the policies concerning updates on consoles unfortunately means Yuri will remain broken.
Any time your character's theme song overrides the background music. That only happens if you've got a good kill-streak going, but when it happens, it's awesome.
Serious Business: Less so than other MOBAs, but the element is there (particularly people who complain on the Awesomenauts wiki about various "broken" mechanics).
Stop Helping Me!: Displacement abilities such as Leon's tongue, Lonestar's bull, Skølldir's caber toss, and Coco's lighting ball can easily allow an enemy to escape an otherwise fatal situation if used incorrectly.
That is to say nothing about when a friendly Lonestar's bull pushes Clunk towards you far faster than you can run away from his Self-Destruct...
That One Map: Opinions on AI Station 404 are fairly split, but a number of players do see it as one.
