Angry young man, Shehenshah, Major Saab or Big B... call him by any name, behind any look and avatar you'll meet the very charismatic, always inspiring and energetic man that legandary Amitabh Bachchan is.

At 71, Amitabh Bachchan, the actor of the millenium's persona is what dreams are made of.

As the mega star of Bollywood celebrates another birthday, let's take a look at some of the avatars he immortalised...

Vijay: Be it the 'angry young man' that Vijay was in Zanjeer or the vengeful Vijay Deenanath Chauhan of Agneepath, he was imeccable.

The character became his secind name as he played Vijay in 20 odd films.

Famous Dialogue: Jab tak baithne ko na kaha jaaye sharafat se khade raho.

Yeh police station hai tumhare baap ka ghar nahi'.

Coolie: Iqbal the flamboyant coolie will remain etched in the memory of every Amitabh Bachchan fan not just for the way Big B carried the role but also because in this film that the actor was critically injured during an action sequence.

It was considered to be Big B's secind life.

Famous Dialogue: 'Bachpan se hai allah ka haath aur allah rakha hai apne saath. Baazu pe hai saat sau chiyasi ka billa, bees number ki beedi peeta hoon, kaam karta hoon coolie ka aur naam hai Iqbal.

Jiske sar pe haath pade bache na uska ek bhi baal.'

Shehenshah: Who cares about Batman and Spiderman when we have very own crusader for life, Shehenshah who comes out when crime raises its head.

Dressed in a leather costume with one iron hand this was one of the most iconic characters played by Big B.

Famous Dialogue: Rishtey mein toh hum tumhare baap lagte hain, naam hai Shehenshah.

Jai in Sholay: A discussion about friends in Hindi movies won't be complete without a mention of Jai, played with utmost perfection by Big B.

Yet another iconic avatar that will be remembered forever.

Famous Dialogue:'Tumhara naam kya hai, Basanti?'

Tiger in Hum: No on could have dared to do do what Amitabh Bachchan did in Hum.

Even the shameless request for kiss by Tiger sounded romantic when it was Big B asking it.

Famous Dialogue: Is duniya mein do tarah ka keeda hote hai. Ek woh jo kachre se uthta hai.

Aur doosra woh jo paap ki gandegi se uthta hai.

Kachre wala keeda insaan ko bimaar kar deta hai.

Magar paap ki gandegi ka keeda saare samaaj ko bimaar kar deta hai.

Kachre ke keede ko maarne ke liye flit bazaar mein milta hai.

Magar paap ke keede ko marne wala flit, saala, bana hi nahi hai aaj tak.'

Narayan Shankar in Mohobbatein: Dressed in black bandhgalas with a red teeka adorning his forehead, Amitabh Bachchan as the no nonsense principle of a Gurukul was a character that confused the audiences by making them hate the actor they loved.

Famous Dialogue:'Parampara, Pratishtha, Anushasan. Yeh iss gurukul ke teen stambh hai.

Yeh woh aadarsh hain jinse hum aapka aane waala kal banaate hain'.

Subhash Nagre in Sarkar: The black lungi-kurta, white mane, red tika and rudraksh, Amitabh Bachchan as Subhash Nagre, a man who commands respect and instills fear at the same time was flawless.

Worth being addressed as Sarkar.

Famous Dialogue: Mujhe jo sahi lagta hai main karta hoon, fir chahe wo bhagwan ke khilaaf ho, kanoon ke khilaf ho ya pure system ke khilaaf.

ACP Darshan in Bunty Aur Babli: Mean, menacing and currupt inspector of Bunty and Babli, Darshan dressed in a leather jacket, aviators with a ciggie between his lips was a treat to watch for Big B's fans, who had so far seen him playing a good cop.

Harish Mishra in The Last Lear: Yet another colourful character played by Big B.

Long while tresses suited him perfectly while playing retired Shakespearean theatre actor who suddenly quit after being on stage for more than thirty years.

Auro in Paa: By far one of the most difficult and most well played character by the legend.

He played a 13 year old boy suffering from a rare disease called Progeria when he was nearing 70! Do you still wanna know the definition of perfection?
