My favorite Tamagotchi is Miraitchi. I also really like Orenetchi, Melodytchi, Himespetchi, Kiraritchi, and plenty of other modern tamagotchi characters.
Tarakotchi. He's been my favourite ever since I failed in an attempt to get a Maskutchi a few years ago and accidentally got a Tarakotchi instead - I think that he's got a lot of personality!
I'm quite fond of the "ugly" Tamagotchi types in general.
I love Mizutamatchi! (well,obviously.)
But I also really like Chamametchi, and Omechuptchi! I saw him when I got my first ON in December and fell in love. He's cute and he looks like my favorite food!
Hi, my favourite Tama is Mametchi, he is my cute main man. He is 138 Tama years old. I also love my other Pix, Lovelitchi. I’m hatching my brand new pix party tomorrow so I will just have to have patience and see who it is!
I will have to say Mametchi currently, even though I feel he is basically the Pikachu of Tamagotchi and I feel really clique choosing him. But he was my first adult Tama ever back in 1997, so he holds a special place for me.
