Purple

Purple is one of the most recurring characters in the series, appearing in all 3 seasons of Algodoo Marble Race, Algicosathlon and its fake sequel, Kart-Race Revolution and Flag Frenzy. She wears a black bow on her head, it used to be dark purple.

Physical Appearance
Purple appears as a purple colored stickfigure wearing a big, black bow on top of her head, like all other female characters, she used to have eyelashes, but they were removed in an Universal Patch Note (a community post by BlueIce57 saying that eyelashes were "banned", when in reality they were just removed from everyone).

In Algodoo Marble Race

 * Purple's first appearance was in Algodoo Marble Race Season 1, where she was just a marble, devoid of any personality or design. Purple survived all the way through Part 4, where she won the Season.
 * Later on, she'd appear in the next season, where she got eliminated in the very first part, at the second round.
 * Purple's still competing in Season 3.

While Competing
Algicosathlon was when Purple started to get recognizeable.

Purple started off getting 8th/24 place in the Race to the Shiny Bowl event.

Because of the terrible course design of BMX Survival, Purple crashed alongside 12 athletes, she got 18th place and fell to 17th/23.

In Day 3, Purple got 10th place and rose to 16th/22.

In Marble Kart, the rope bumped Purple nearly offstage, she placed 14th and stayed at 16th/21.

In Excavation, Purple did bad, with a time of 44.18 seconds, she got 17th/20. and fell to last place (incorrectly displayed as 19th place), since that elimination was vote based with the bottom six, Purple (and by extension, Tan, who was in 19th), were let off the hook in favor of Magenta and Olive. However Purple was still in last.

In Day 6's team event Archery, Purple was grouped in Team Shiver alongside the other 'cold' colors, in the event itself, Purple killed Yellow and was incapacitated by Orange, her team still won because Team Shiver had 6 members, whereas Team Blaze (the warm color team) only had 3. Purple won 200 points and rose 2 ranks. In Skiing, also in Day 6, she got 6th place, rising her rank to 11th/18.

In Long Jump, Purple seemed to have a pretty solid jump at first, but she suddenly started going backwards, she landed at the 60m mark, she placed second to last. She fell to 15th/17.

In Laser Tag Battle, Purple got 3rd place in her group battle with Red, Pink and Brick. and 9th in the event. She got eliminated alongside Gold. She was originally set to rest at 15th place, but got boosted down to 16th after Magenta rejoined, and then again to 17th when Green rejoined.

Not Competing
In the very start of Algicosathlon Day 12, there's a comic featuring Purple, White and Lime in the Fancy Jail. Purple screams at Lime for setting up a rejoin with the sole purpose of getting White out of the jail, presumably so Lime and Purple could be together (which also means that Purple and White spend a lot of time together, much to Lime's annoyance). Lime reveals that he did it because he has a crush on Purple, which surprises both of them, but the latter already knew. Purple sighs and reveals that she's dating White, causing Lime to collapse.

In the very last event, the Fancy Jail broke, causing the host to make Purple and everyone else compete with the finalists. Since the teams were sorted on how much you and the finalist looked like, Purple obviously teamed with Lavender, however she didn't help much, Purple was the 3rd person to be defeated and the 2nd on her team.

Purple got awarded no medals (as no team medals were awarded) and left Algicosathlon with $41060.

In conclusion, Purple was a pretty mediocre athlete whose ranks were always around the middle, and ended up getting eliminated in Day 8, in the middle of Algicosathlon.

In Kart-Race Revolution
In the first course of Kart-Race, Purple got first place, but solely due to the boss' interference. She got 30 points for getting first.

In the second course, Purple finished at 12th and got 9 points, bringing her total to 39 points, lowering her rank to 3rd, being beaten only by Teal and Pink.

In Flag Frenzy
In Flag Frenzy, Purple lost to Olive in the first round.

 * So far, Purple is the only character who is confirmed to be in a relationship.
