first at all i want to thanks those who took time to write this guide, i will also contribute to this i know i dont have any recognition in the gaming scene, while i lack tournament experience, i have some undestanding of the game mechaninism that some may find usefull, so i will contribute with what i know.
soki
the soki player have the worst time with gigants although as any other character he has his way to overcome this situation, level 1 supers and level 3 super are useless with gigants, while purification sword have a nice damage output on either gigant, it is punishable whether is block or not a gigant can get to you fairly easy so forget about super with soki, also oni transformation have super armor, but gigants break that super armor, counter moves will get you kill so forget about them, your best tool against gigants here is soki long range attack that goes to launcher, countering every move, a gigant does with launcher super jump attack jump cancel run is your best way to survive and win
morrigan
vector drain, and soul fist are your best friends here, dont overabuse vector drain, remember while both gigants can be command grab they can jump out off it and punish you badly, vector drain is best use as a counter move, why? grabs are use to stop momentum on the gigants, on PTX-40A use vector drain to counter his jab’s but be careful againt tackle baroque into grab or overhead, this is a 50/50, try to predict ground moves and counter them with vector drain, do have special care with PTX overhead air move, since this can be easily baroque cancel into another overhead, that does insane damage if it connect, super jump and try to stay in angle to throw soul fist, at long range, avoid close to mid soul fist, since both gigants have tool to punish and get near you at this situation, also drill kick is useful to get a fast 4.7k damage on gigants went they do laggy moves, since drill kick have a good recovery is a good option to make some damage get on the ground an go for vector drain, level 3 super is best use to evade dificult situation, such is the case of PTX unblockeable setups, generally capitalize on whiff moves, and play defensively morrigan cant take much damage but still have a good oportunity againts gigants
yatterman-1
long range move, and a good mixups are your friends here, at long range kenda magic is great, comes out fast, at its extremely difficult to punish, if engage in close, yatterman level 1 super yatter-wan kamizake is the best tool to get out of trouble, also get you is a point were you could easily super jump, and go for jumping hammer smash jump cancel an get out of there, or try a cross up and cancel it to yatter-wan to avoid punish, stay defensive and abuse your long range moves to archive victory also kick shock combo may come in handy since it can but a gigant just where you want
yatterman-2
almost the same strategy as chun-li(thanks to GCYoshi for providing the chun-li strategy), only big diferent is that yatterman-2 have tool for long range situation, so she can keep the runaway game, level 1 super summond friend is fairly good, since it will do an average amount of damage, yatter splash can slow down your falling so you want to use it whenever your above a gigant, try to build as much super bar, as posible since those are your wild card against both gigants yatter splash and spark fireball are the best for building bars
Zero
charge buster, level 3 super are usually what you will see amount zero players, but there’s more you can do, went this 2 option by itself arent enough, zero must keep the charge buster at all times, also teleport moves are crucial to zero mixups game on gigants, on air go for 5C cancel into hyenkyaku use hard version to get on a safe point shoot the charge buster an quickly get out of there, level 3 super is best used to counter gigants aproches, remember keep in mind any normal zero does on ground can be special cancel into hyenyaku into charge into back dash , so keep yourself safe, zero cant stand to get hit one combo for both gigant are destructive to zero, so stay out of their range is posible, but if need give a try on hyenkyaku it may do wonders.
Tekkaman blade
crash intrude, falchion, and baselard are your main tool for this, dont overabuse baselard, any gigant pro will eventually see them coming, ones that happen they will punish badly for everyone of them, try to get in close hit ones and throw baselard this is the best way to get a knockdown, went knockdown use falchion to get across them if falchion hit cancel into crash intrude, them go for a stap OTG, if your gigants get on dizzy state, go for launcher into tekkaman blade advanced combo, it work the same as normal chars, punish every laggy move with crash intrude, or hit cancel to baselard, to get a knockdown, careful with gigants if they have baroque, since they can easily go for powerful mixups and big damage, play defensive went need, but try to stay on the offense get possible.
