Legendary Characters

I saw people getting legendary item from a 15k pack. But in the end I guess it just rng.

After you beat story mode you unlock infinity mode which getting high amount of infinity gems or something people guess over 20k you have a chance to get a legendary piece. Dunno about packs.

There are "party" legendary" characters and then there are "Normal" legendary".  characters. The "party" legendary characters can only be unlocked by getting 25,000 time shards or higher in the infinity survival and getting to wave 25+. Whether that is the best or only way to get them is unknown but it appears to be the most efficient way. Now the "normal" legendary items can only be obtained from sticker packs costing 15,000 or more coins. You can also get legendary character pieces for iron citron and the toxic super brains from these. You might be able to get other legendary characters from packs but i don't know for sure.

I got some legendary parts of characters from 35k packs... but im sure you can get them from 15k packs as well.

I got part of the scientist out of a 15k pack two days ago.

Just to clarify about the types of Legendary characters that you could get. 1) Normal Legendary character stickers that you get from sticker pack and 2) Party Legendary which you can only get by completing 25 wave + and earning 25k+ shards in Infinity Time Mode.

Basically there are only 4 Normal Legendaries characters (2 in Plants and 2 in Zombies)  that you could unlock from sticker packs. Once you unlocked them don't bother opening the sticker packs again for their parts, instead do the Infinity Time Mode to unlock those Party Legendaries.
