Manga existence for a bet

[sco6_4km]

ok, i have done a stupid bet with a friend, to know if some tv anime were based in their respectic manga.
this is the list

1- Shura no toki (no shura no mon)
2- Bakuretsu Tenshi
3- Gundam wing
4- Samurai 7
5- Mazinger Z

i'm pretty sure none of those is based on a manga. tho i'm not 100% about Mazinger Z and Shura no Toki tho

[PSJ]

im positive that samurai 7 and gundam wing isnt based on mangas. i believe there is a bakuretsu tenshi manga but im not sure and i dont know about the other 2.
